Pragma Unsuppress

Syntax:

pragma Unsuppress (IDENTIFIER [, [On =>] NAME]);

This pragma undoes the effect of a previous pragma Suppress. If
there is no corresponding pragma Suppress in effect, it has no
effect. The range of the effect is the same as for pragma
Suppress. The meaning of the arguments is identical to that used
in pragma Suppress.

One important application is to ensure that checks are on in cases where
code depends on the checks for its correct functioning, so that the code
will compile correctly even if the compiler switches are set to suppress
checks.
